Drag-n-Drop
to upload your archive
ZIP Viewer
Open a ZIP file online and see what is inside
Drop in a .zip and get the full file list straight away: every name, its real size, how well it compressed and when it was last changed. The archive is read in your browser and never uploaded, and nothing is extracted to disk, so you can check what a ZIP holds before you trust it.
Click Open ZIP file, drag a .zip onto this panel, or press Sample to see a small archive listed.
| Name | Size | Packed | Saved | Method | Modified | Preview |

See inside without extracting
A ZIP keeps an index of its own contents at the end of the file, and that is all this tool reads. You get the complete list instantly, even from a large archive, with nothing unpacked onto your disk.
-
Runs in your browser
The archive is parsed on your own machine and never sent to Static.app, so a ZIP full of client work or personal documents stays where it is. Nothing is stored and nothing is scanned.
-
Compression at a glance
Every entry shows its real size next to its packed size and the percentage saved, with the compression method named. Handy for spotting the one uncompressed image that is making an archive far bigger than it needs to be.
How to open a ZIP file online
-
1
Open your archive: click 'Open ZIP file' and pick it, or drag the .zip straight onto the panel.
-
2
Read the contents: sort by name, size or date, and press 'View' on any text file to read it without unpacking the archive.
-
3
Check it will publish: the viewer says whether index.html sits at the top level, then you can upload the same ZIP to Static.app as a live website.
Supported file types
Open a file from your computer or drag one in. The viewer accepts:
RAR, 7z, TAR and TAR.GZ are different formats and are not readable here, so the viewer says so plainly instead of failing quietly. Encrypted entries are listed by name and size but cannot be previewed. Everything happens in your browser and nothing is uploaded.
Working with a different kind of file? Static.app has a tool for each:
How Static.app's ZIP Viewer compares
ezyZip, Archive Extractor and tiiny.host all handle archives in the browser era in different ways. Here is an honest read of where each one fits.
| Static.app | ezyZip | Archive Extractor | tiiny.host ZIP viewer | |
|---|---|---|---|---|
| List a ZIP for free | Yes | Yes | Yes | Yes |
| Reads without uploading the archiveezyZip also works in the browser; Archive Extractor sends the file to its servers. | Yes (nothing leaves your device) | Yes | No (uploads to server) | No (uploads to host) |
| Extract files to diskThe clearest gap. This is a viewer: it lists and previews, it does not unpack. | No (view and preview only) | Yes | Yes | Serves them as a site |
| Handles RAR, 7z, TARBoth of those are general archive tools; this one is ZIP only and says so. | No (ZIP and ZIP64 only) | Yes (many formats) | Yes (many formats) | No |
| ZIP64 support for very large archives | Yes | Yes | Yes | Not stated |
| Compression ratio per entry | Yes (size, packed, saved, method) | Size only | Size only | Not shown |
| Preview a text file inside the archive | Yes (text entries) | Yes (some types) | Yes (some types) | No |
| Warns when the archive will not publish as a siteNothing else here checks for a top-level index.html, which is the usual reason a ZIP upload appears broken. | Yes | No | No | No |
| Publish the ZIP as a live website | Yes (free subdomain and SSL) | No | No | Yes |
| Best for | Checking an archive, then hosting it | Extracting many formats | Extracting a large archive | Serving a ZIP as a page |
If you need to unpack an archive, or it is a RAR or a 7z, ezyZip and Archive Extractor are the right tools and this page will tell you so rather than fail quietly. What this viewer adds is a complete listing without uploading anything, the compression detail per entry, and a straight answer on whether the archive is built correctly to publish as a website.

Frequently asked questions
Is this ZIP viewer free?
Yes. Listing and previewing an archive is free, with no signup and no account. Publishing the archive as a live website is free for 7 days on a free subdomain with an SSL certificate and no credit card required, after which keeping the site online needs a paid plan.
Is my archive uploaded anywhere?
No. A ZIP stores an index of its own contents at the end of the file, and that index is read in your browser. The archive is never sent to Static.app, never stored and never scanned. Opening one with your network disconnected still works, which is the easiest way to check.
How can it list a large ZIP so quickly?
Because it does not extract anything. Every ZIP ends with a central directory listing each entry with its name, sizes, compression method and date. Reading that is a few kilobytes of work no matter how big the archive is, so a listing appears immediately even for an archive with tens of thousands of files.
Can I open RAR, 7z or TAR.GZ files?
No. Those are different formats with different structures, and this viewer reads ZIP only, including ZIP64 for archives over 4 GB. If you open one of them the tool says so plainly rather than showing an empty list. For those formats use a general archive tool such as ezyZip or 7-Zip.
Can I extract files from the archive?
Not to your disk. You can preview text entries such as HTML, CSS, JavaScript, JSON, XML and Markdown directly in the page, which covers checking what is inside. Extracting everything is a job for your operating system, which already opens ZIP files, or for a dedicated extractor.
What does the "will this ZIP publish as a website" check do?
It looks for an index.html at the top level of the archive, which is what a hosted site needs as its entry point. The usual mistake is compressing the folder that holds your files instead of the files themselves, which buries index.html one level down and produces a site that will not load. The check also flags password-protected entries, archives over the 50 MB free-trial limit, and leftover macOS or Windows metadata.
Why can some entries not be previewed?
Three reasons. Password-protected entries cannot be read at all without the password. Entries compressed with something other than Deflate or Stored, such as BZip2 or LZMA, are listed but not decoded here. And on an older browser without the built-in DecompressionStream support, only uncompressed entries can be previewed. In every case the listing itself stays accurate.
Can I turn my ZIP into a website?
Yes, that is what Static.app does. Once the check above passes, drop the same archive on the upload box and its contents are served as a website at their own address with an SSL certificate. The uploader takes ZIP archives, which is why a loose .html file is not accepted.
